Application March 11; 1939, serial No. 261,391 v 9 Claims. (o1.;1

This invention relates generally to surface drains, and moreparticularly to drains which prevent refuse and the like from passing tothe main drain line to which the drain is connected.

means for directing the how of liquid to the center of the restrainingmeans or bucket. I

- It is accordingly, an object of my invention to overcome the above andother defects in drains and more particularly to provide a drain whichis simple in construction, efiici'ent in operation,

cheap in cost, and easy toinstall.

'Another object of my invention is to provide a surface drain whereinmeans are provided for indicating the clogging of the straining memberof the drain Without flooding the drained surface. Another object of myinvention is to provide a surface drain which has a cover designed tometer the flow of fluid to the drain and to direct the drained water tothe central portion of the drain structure. Another object of myinvention is to provide a simple means for removing the strained refusefrom the drain,

Another object of my invention is toprovide a surface drain which hasall parts thereof remov ablcthrough the inlet opening.

Another object of my invention is'tofprovide surface drain wherein theparts thereof are. so, disposed that a metering aperture is provided torestrain solids but permitting a predetermined flow of fluidtherethrough.

Another object of myinvention is'to provide a surface drain whereinthemetering aperture: below the surface of the drain cover and is protected by the initial straining means orperforated cover. d d

Other objects of my invention will become evident from the followingdetailed description, taken in conjunction with the accompanyingdrawing, in which Fig. l is a plan view with parts broken away of mynovel surface drain.

Fig. 2 is a side elevational view with parts broken awayofmy novelsurface drain connected td'a drain line.

-R'eferring to the drawing, my novel surface drain comprisesgene'rallyan outer cylindrical member I having an inlet and an outlet, a solidsretaining-member 2,, and a cover 3 having tapered slots 4. Theg'outercylindrical member I has an offset portionv Er providing a shoulder 65.An outwardly 'and upwardl y, extending portion I with a plurality ofprojecting members 8 provide anchoring means for the drain andfurthermore directs theseepage into the drain line through theaperturesflin thee-cylindrical member I. The

bottom portion ID of the'cylindrical member I is flanged inwardly and aninteriorly threaded aperture I i is formed to engage a drain line l2 todrain the liquid fromthe surface of. the floor to I be drained.

The solids'retaining member 2 is cup-shaped in form and-the sidesthereofhave apertures I3 to U permit the lateral flow of fluid passing throughthe drain. while retaining the solids in the solids retaining member 2-.A few' small apertures I I are disposed in the bottom of the solidsretaining member 2 to permitbetter flow of fluid throughthe drain. Thesolids retaining. member 2 is. disposed in spaced relation with the sideand bottom portions of the cylindrical member l by means of annular ringmember I5 and brackets I5 connecting thering member I5 and the outersurface of the'solidsretainingmember I. The annular ring member I5 restson the shoulder 6 of the cylindrical'member I and Supports the solidsretaining-member 2 in spaced relation with the sides and bottom of thecylindrical member I. A

slotted cover 3 has a wide rim or border portion I! extendingto theinterior surface of the solids retaining member 2 in order'that thefluid will not flow directly to the drain line I2 without passingthrough the solids retaining member 2.

' An annular shaped aperture I 8 is provided be tween the bottom portionof the cover 3 and the top of the retaining member 2 in'o'rder that thefluid may'pass to th'e'drain line I2 when the apertures I 3 ofth'e'solids retainingmember 2 becomes clogged. The wldth of this aperture I8is such that a noticeable amount of fluid will be backed up tonoticeably cover the slottedcover 3 inorder that? notice maybe giventhat'th'e solids retaining member 2 is clogged and must, be removed. Theannular aperture I8 is protectedby the cover 3 and is such width thatordinary solids will not pass therethrough. The tapered slots 4 in thecover 3 tend to direct the fluid passing intovthe drain directly to thecenter of the solids retaining member 2 thereby increasing the eficiencyof the solids retaining member 2 in that the solids will strike anunperforated portion of the solids retaining member 2 and the fluid willmove outwardly laterally therefrom. By removing the cover 3, it will beevident that the solids retaining member 2 may be very simply removed. Ig I In operation, the tapered slots 4 in the cover 3 causes the fluidentering the drain to'flow to the center of the solids retaining member2 wherein it flows laterally outwardly through the apertures l3, thesolids being retained in the solids retaining member 2. When theapertures [3 of the solids retaining member 2 become clogged, the fluidwill overflow the solids retaining member .2 and pass through theannular aperture I8 to the drain line l2. The annular aperture l8 willnot permit solids to pass therethrough and it will further cause thebacking up of the fluid so that it will overflow-the cover 3 and givenotice that the apertures l3 are clogged and that the solids retainingmember 2 must be removed. The removal of the solids retaining member 2is evident from inspection of the drawing.

It will be evident that I have provided a surface drain which is simplein construction, easy to clean, efficient in operation, and operableafter clogging of the solids retaining member 2 with means for givingnotice of the'clogged condition of the retaining member.

Various changes may be made in the specific embodiment of the presentinvention without departing from the spirit thereof, or from the scopeof the appended claims.

What I claim is:

1. A surface drain of the class described, in combination, a memberhaving an inlet and an outlet, a solids retaining member disposedcentrally of said first mentioned member having the sides thereofperforated to permit the lateral flow of fluid, a slotted cover for saidfirst mentioned member disposed to provide an annular aperture betweenthe top of the solids retaining member and said cover whereby fluid maypass therethrough to the outlet of said first member 2. A surface drainas set forth in claim 1 wherein the slots in said cover are tapered todirect the fluid to the center of said solids re.- taining member.

'3. A surface drain as set forth in claim I wherein said first mentionedmember has an outwardly extending flange to direct seepage to saidoutlet of said first mentioned member.

,4. A surface drain of the class described, in combination, acylindrical member having an inlet and an outlet, a solids retainingmember disposed in said cylindrical member in spaced relation with thesides thereof, and a slotted cover having a wide rim portion wherebyfluid can pass only to said solids retaining member, said cover and saidsolids retaining member being disposed to provide an annular aperturefor the flow of fluid to said outlet of said cylindrical member whensaid solids retaining member becomes clogged I 5. A surface drain of theclass described, in

perforations in said solids retaining member become clogged.

6. In a surface drain, in combination, a cylindrical member having aninlet and an outlet, said cylindrical member having the upper portionthereof offset to form ashoulder, a solids retaining member havingoutwardly projecting portions engaging said shoulder of said cylindricalmember to support said solids retaining member in spaced relation withsaid cylindrical member, and a perforated covercarried. by saidout-vwardly projecting portion of said solids retaining member disposed todirect all fluid into said solids retaining member, said cover and thetop of said solids retaining ,member forming an annular aperture wherebyfluids may flow therethrough to said outlet when the apertures in saidsolids retaining member become clogged.

7. A surface drain as set forth in claim ,6 wherein the slots in thecover are tapered to direct the fluid to the center of saidsolidsretaining member. 1 v

8. In a surface drain, in combination, a cylindrical member havinganinlet and an outlet and an inner shoulder on the upper. portion thereof,a solids retaining member having perforated sides and an outwardlyprojecting portion for engaging said shoulder to support said solids retaining member in spaced relation with the in-- the inlet of saidcylindrical member, the widerimmed portion of said cover and the top ofsaid solids retaining member forming an annular aperture for the flow offluid to said outlet of said cylindrical member when the perforations ofsaid solids retaining member are clogged while retaining solids in saidsolids retaining member.
